PATENT OFFICE l 2 Claims.

This invention relates to window sections. This invention has utility especially in connection with vitreous or glass panes having fused framing therefor which may be assembled into 5 sealed air chamber panels adapted for tempera.-

ture insulation.

Referring to the drawing: Fig. 1 is a side view, with parts broken away, of a panel unit; Fig. 2 is a section on the line II-III, Fig. 1;

. Fig. 3 is a perspective view of a frame with partial pane therein;

Fig 4 is a section through a frame assembly having departure inthe o'set between the flanges from that in Fig. 2;

Fig.. 5 is a fragmentary View of panel assembly with supplemental gasket sealing in addition to the bonding therebetween;

Fig. 6 yis a section on the line ITI-VI, Fig. 5; and

Fig. 7 is a section at the frame involving a plurality of air chambers for the unit.

.These units for the frames desirably are oilset to provide outer flange I, inner flange 2, intermediate offset 3, wherein the flange 2 and offset 3 vprovide a seat for pane 4. This structural shape of the flanges I, 2, and intermediate oilset 3 is of sheet metal and of'Z-shape crosssection. In the assembly herein as of glass, the

flange 2 and seat 3 are desirably surface coated with bonding agenti as the solder of J. Bhowles MacLean, Patent No. 2,035,241,V of March 24,

This unit between the pane 4 and frame'is I further perfected (1)' at corners or groovesl therebetween by supplemental metal or solderbonding 6 at the terminal portion of the flange 2, and

(2) at endless solder or fused portion I at the oilset 3 adjacent the opposite sides of the pane 4 4o from that having the bonding I. It is thus seen that there is endless seat at the offset 3: endless bonding along said surface, as endless union 5 therebetween, supplemented by the reinforcing bondings 8, 1. 'I'here is thus a framed element.

45 Such may be Vassociated with a .complementary element to place, as a tin-like extension: the flanges I in opposed seating relation.

In this assembly there may be yieldable spacing means as cork gasket element 3 introduced:

' 50 then as between these flanges I, such may be vsurfaced with bonding solder 3 therebetween. This completes a panel unit or lglazing section armored peripherallyfor insertion in a standard frame or structural unit, whether for a window 55 in a building, in a `vehicle, or refrigerator, and whether or not vilxed with such structure or mounted in a movable section. 'Ihe diaphonous element 4 may be selected either for color or for transmitting lselected rays as to actinic effect. Furthermore, the character thereof, whether sheet orv plate, and whether thin or heavy, may 5 be adapted'for that of the ultimate installation. The compressible packing 8 desirably has thereon shellac I0 as a binding agent against shifting relatively to one of the panes 4. 'I'his binding agent holds the packing 8 against shifting into 10 air chamber II between the panes of the unit. e In lieu of the abruptofrset 3, there may be tapered onset I2 (Fig. 4). 'I'his is a cushioning form of construction avoiding strains from ex; pansion and contraction, although experience 15 with the solder as the bonding agent between the metal and pane has, with thin sheet metal framing, been eil'ective for such holding as to maintain sealing of the air chamber II under wide temperature changes. 20

The outer ange I of these panel units as away from the pane proper may have openings I3 (Fig. 6) therein to receive assembly screw I4, thereby to effect gripping of wafer or cork gasket seal I5. There is thus a cushioning assembly, 25 and these screws I4 may be supplementally sealed by solder I6 and the bonding completed byvperipheral-solder I1.

To this end, compressible packing I3 may be continuous Vor endless as 'to intermediate panes 30 I9, znfinspacing therefrom the outerv panes 4,

therebyproviding intermediate air'chambers 2|,

22, 22, instead 0f the single air chamber Il. The

' outer panels 4 may have full bond sealing with the frame.' Withthis grouping for' the unit, the 35 outer danses I may, inlieu .of surface bonding, have terminal bondingzltas a recess filler.

Solder 25 may be at'the heads oi' the screws I4. What is claimed and itis desired to secure by United States Letters Patent is: g 40 1. A double glazed panel comprisingl two similar metal frames ot'Z cross-section having a pane in the oll'set portion of each frame and soldered to said frame, resilient spacing means between said panes, a separate continuousgasket between the outermost ilanges ot the frames, and

an independent seal of solder about the periphery oi' the assembly.

2.,A double glazed panel comprising two similar metal frames of Z vcross-section having a pane in the onset portion of each frame and soldered to said frame, resilient spacing means between' said panes, and an independent seal of solder about the periphery of the assembly.
